everythinginsidethefence.compolypropylene has better stress crack resistance and low temperature toughness than homopolymer at the expense of small reductions in other properties. Most Chemline valves and all the pipe fittings are PP-R. PP-R pipe is also available. The working temperature range of Chemline’s PP-R ball valves is –20 to 80°C (–4 to 176°F) and up to ...

www.lyondellbasell.com― Impact Copolymers: Polypropylene impact copolymers are thermoplastic resins produced through the polymerization of propylene and ethylene or butylene. Their synthesis consists of a heterophasic amorphous structure inside a semi-crystalline PP homopolymer matrix providing high impact properties and thermal resistance. Due to their broad

Syndio-tactic and iso-tactic polymers have symmetry so can be explained as linear polymers. Effect of Block co-polymerization will depend on type of block present in the polymer system.

www.lyondellbasell.comFor homopolymer polyethylenes, the higher the resin density, the higher the degree of crystallinity. High density PE resins have molecular chains with comparatively few side chain branches. This allows the chains to pack more closely together. The result is crystallinity up to 85%. Low density PE resins generally have crystallinity from 35 to 55%.
